Relay outputs
All relays are shown in the open position.
FAN is normally on. In an alarm, the sum
alarm is activated and 10-11 closes for
example.
Damper connection
Fire/smoke dampers are connected as shown in
the diagram above.
Evacuation dampers
(Only relevant in network mode)
If evacuation dampers are used, they should be
connected as usual. Evacuation dampers are
then defined in the KSUA, which monitors
their position. Evacuation dampers are
normally closed, and are opened if there is an
alarm. The damper motor closes the damper
and the spring return opens it.
This is only
relevant in network mode. In stand-alone
mode, evacuation dampers cannot be fully
operated.
Diagram showing connection of Belimo BSIA / BR24-F-ST to KSUG. Remember that jumper F must
be ON and 8 OFF in stand alone mode. In network mode jumper F must be ON and G OFF.
Smoke detector inputs
The two smoke detector inputs are designed
for a loop resistance of 2200 ohm (terminating
resistor). Unused detector inputs are
terminated with a resistor connected directly to
the terminal. 2200 ohm, power at least 0.6 W.
See also the description of jumper settings.
Cable type for connections
The smoke detectors are connected with
twisted-pair cable separated from other parts.
Telephone type cable is used, with no
particular requirements in terms of area.
For example, the actuator can be connected
with 5*0.5mm
2
if the distance between the
actuator and the KSUG is less than 100
metres. If the distance is greater, a larger area
is required.
Fuses
There is a 160 mAT fuse on the motherboard.
The fuse is to the right of the mains
transformer. The holder is the bayonet type.
To remove the fuse, press down and turn a
quarter turn anticlockwise.
